14 Claims.

This invention relates to an improvement in window fasteners of the typeemployed for fastening the upper and lower sash together, in which afastening device extends transversely through one of the sash and intothe adjacent edge of the other sash. i

Heretofore, a difliculty has been encountered in matching the holes ofthe adjacent edges of the sash to receive a fastening member therefor,and the holes are sometimes formed too large or not true in size .andlocation, with the result that the fastening member would not snugly fitthe holes in the sash.

'Ihe object of my invention is to provide an expansible fastening devicecapable of being expanded to fit the holes formed in the adjacent edgesof the sash and thereby obtain a proper lit, avoiding unnecessaryrattling and jamming of the parts.

This object is .accomplished in the preferred embodiment of theinvention by the provision of expansible members backed up by Iyieldablebushings, and by the provision of an expansible securing bolt capable offitting in the tubular members when the latter are expanded into placein the adjacent edges of the sash.

I have illustrated a preferred embodiment of the invention in theaccompanying drawing, in

which:

Fig. l is a vertical sectional view of the adjacent edges of the windowsash, showing the invention applied thereto, partly in elevation;

Fig. 2 is a face view thereof;

Fig. 3 is a View similar to Fig. 1, but enlarged and having parts of thefastening in section;

Fig. 4 is a transverse sectional view on the line 4-4, of Fig. 3;

Fig. 5 is a side elevation of the fastening bolt removed;

Fig. 6 is a side elevation of the guide sleeve;

Fig. '7 is an end elevation thereof;

Fig. 8 is a vertical sectional view of the corrugated socket; and

Fig. 9 is an end elevation thereof.

The invention is shown as applied to the adjacent edges of upper andlower window sash designated by the numerals I and 2, respectively, andwhich have holes or openings 3 and 4, formed therein to receive thewindow fastening; If these holes are not formed of exactly the rightsize to t the fastening member inserted therein, or if they are not inproper alignment when the sash are closed, the fastening device will notfit snugly with the result of rattling and insecure fastening of thewindow.

In order to avoid this objection, I have provided an expansible socket 5in the sash I, which socket is made in two parts, as shown in Figs. 8and 9, so as to be expanded to fit the hole snugly. Topermit of suchexpansible'action, a bushing 6 of yieldable material, such as softrubber, is placed in the hole 3, within which the split socket 5 isdisposed. The socket 5 is provided with flanges 1 on its inner end to besecured by screws 8 to the sash I.

The opening 4 in the sash 2 has a split sleeve 9 extending therethrough.'This sleeve 9 is likewise in two parts, as shown in Figs. 6 and 7, soas to be expanded to snugly t the hole 4, but between the' sleeve 9 andthe surface of the hole 4 is a .yieldable bushing I0, such as rubber,which permits the expansion of the sleeve 9 tofit the hole. The innerend of the sleeve 9 has flanges I I thereon, to receive fastening screwsI2 for securing the parts of the guide sleeve 9 to the sash 2.

A fastening bolt I3 is adapted to extend through the sleeve 9 and intothe socket 5 for securing the sash together. This lfastening bolt I3 is'likewise expansible, being formed as a rolled tube, -2

I6 for intertting with the corrugations I5 in the socket to form a tightconnection therebetween, to hold the fastening bolt in place and tosecurely fasten the window sash.

In assembling this fastening device, the holes 3 .and 4 are bored in thesash, after which the rubber bushing 6 is inserted into the hole 3 andthe socket 5 inserted in the bushing 6 and expanded to tightly fit thehole, after which the screws 8 are inserted to fasten the sections ofthe socket 5 in place.

In a similar manner, the rubber bushing Ill is inserted into the hole 4and the sections of the guide sleeve 9 are introduced therein and expanded to fit this hole tightly, after which the screws I2 are insertedto hold the sections of the sleeve 9 in place. Then the fastening boltI3 is passed through the sleeve 9 and into the socket 5, and is expandedas much as necessary to conform permanently to the expanded size of thesleeve 9 and socket 5 and has its male corrugaelements adapted to belocated in separate openv ings, and a fastening bolt extending into saidguide elements and expansible approximatelythroughout its length to fitthe respective expansible guide elements when expanded.
